Introduction:

We can study the motion of objects by looking at three quantities as time goes on: Position, Velocity, and Acceleration. Newton's Laws of Motion put these ideas together in a straightforward way.

Activity:

• Click on the image to try the Filing Cabinet simulation. Try a standard sequence of pushes using each of the three graphing options. See what you notice!

• Periods 3, 4/5, & 10

Conclusion:

You will need to be good at "translating" these graphs. Here are some questions for practice:

Period 2 & 9

Periods 3, 45, 10

• Can you pause the simulation when the filing cabinet is changing direction? What did the V-t graph look like then?
• Can you pause the simulation when the filing cabinet is at peak speed? What did the V-t graph look like then?
• Can you tell when the filing cabinet is not moving? What did you look for?
• Can you tell when the filing cabinet is coasting? What did you look for?

Practice:

• The following video clips show a Velocity-Time graph. Before you play the video, practice predicting what motion you THINK will cause a graph with that shape.

Enrichment:

• Visit the share drive for video clips of a speedometer. We will use the data contained in these videos in tomorrow's lesson.
